Prenatal nutrition and the risk of adult obesity: Long-term effects of nutrition on epigenetic mechanisms regulating gene expression

Solid epidemiological evidence indicates that part of the risk of obesity in adulthood could be programmed during prenatal development by the quality of maternal nutrition. Nevertheless, the molecular mechanisms involved are mostly unknown, which hinders our capacity to develop effective intervention policies. Here, we discuss the hypothesis that mechanisms underlying prenatal programming of adult risk are epigenetic and sensitive to...
